abstract: The study of compatibility relationships in the system CaO-SiO2-Fe2O3-FeO was carried out in air at constant CaO/SiO2 molar ratio using a thermobalance and the ceramographic method. Also X-ray difraction data were obtained to confirm the coexistence of three condensed phases over a range of temperatures and compositions. In the quaternary system, the liquidus isobaric determined in air is a surface and its intersection with the constant CaO/SiO2 plane is a line on the composition triangle CaO.SiO2-Fe2O3-FeO.

L'étude de la compatibilité des phases dans le système CaO-SiO2-Fe2O3-FeO a été réalisée dans l'air et pour un rapport molaire CaO/SiO2 constant au moyen de méthodes thermogravimétriques et céramographiques. Des données de diffraction des rayons-X ont été obtenues et confirment la coexistence de trois phases condensées dans un domaine de températures et de compositions. Dans le système quaternaire le liquidus isobare est une surface dont l'intersection avec le plan CaO/SiO2 constant est une ligne contenue dans le triangle de composition CaO.SiO2-Fe2O3-FeO.
